- Portable
说明
- Bank control is provided by P1.0-3, decoded by 4 AND gates, requiring only a single IC package. When A15 is low, the device is forced to access only the lower 32kB of memory. This removes the need for software intervention when accessing the interrupt vector table in low memory. This example uses an 27C040 512KB EPROM
